Abstract

The invention describes a solar generation method involving a system (1) that comprises a set of solar cells (2) connected to an inverter (4), which transmits the energy generated to an electrical grid (6), which comprises controlling the active and reactive power that the system (1) transmits to the electrical grid (6) by controlling the voltage (Vcel) of the cells (2) and the output current (Iinv ) of the inverter (4), such that: in a first operating mode, the voltage (Vcel ) of the cells (2) provides the maximum active power in accordance with the operating conditions; and, in a second operating mode, the voltage (Vcel ) in the cells (2) is different from the voltage that provides the maximum active power, an active power lower than the maximum being generated in order to optimize integration of the solar generation system (1) with the electrical grid (6).
